▎ 摘  要

NOVELTY - The elecrode has a first layer that comprises a first particles. A second layer comprises a conductive nanowires. A third layer (108) comprises a second particles. A second layer is arranged between in electrical contact with the first layer and the third layer. The first particles and the second particles comprises a selected from the group of particles of atomically thin material, metal oxide particles and metal nanoparticles functionalized with charged ligands. The first particles and the second particles comprises graphene oxide (GO) particles and the conductive nanowires comprise silver nanowires (AgNW). A transparency of the electrode is greater than 50% for wavelength of light with a wavelength between 350 nm and 700 nm. USE - Electrode used in devices such as solar cell, display, touch screen and transparent heater. ADVANTAGE - The novel stabilization behavior enabled by the presence of GO that prevents abrupt divergence of the resistance to the medium wave (MW) range experienced by bare AgNW networks. The thick GO layer offering increased chemical and electrical stability at elevated temperatures and high voltages and used at the top when integrating this film in transparent heater while ultrathin GO layer is used as interfacial layer in solar cells as a way to enable Ohmic transport and optimize the energy level matching with other layers. The electrophoretic deposition (EPD) provides low cost, rapidity, simple equipment, controllable deposition rate and uniformity of deposition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of forming electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the method for formation and transfer of transparent electrode.
